THE INNER DEVELOPMENT OF THE MOVING PICTURES It was indeed not an external technical advance only which led from Edison's half a minute show of the little boy who turns on the hose to the "Daughter of Neptune," or "Quo Vadis," or "Cabiria," and many another performance which fills an evening.

The advance was first of all internal; it was an esthetic idea.

Yet even this does not tell the whole story of the inner growth of the moving pictures, as it points only to the progress of the photoplay.

It leaves out of account the fact that the moving pictures appeal not merely to the imagination, but that they bring their message also to the intellect.

They aim toward instruction and information.
